The charge/blocking foul grey area and how referees use it to favor the home team is the reason basketball will always play second fiddle to football as a spectator sport. While in football there will also be the occasional home cooking (Crable roughing Smith *cough*), the frequency we see it in college basketball makes it that games at certain venues are almost unwatchable, such as games at Assembly and Cameron.
The charge on Parker that went as an And 1, and the last second charge on C.J. Fair where he lept as the Dukie was setting his feet and should have been a no call, are just the latest in what could be a list of at least 1,000 home cooked charge/block calls I've witnessed in my life. In my opinion it literally ruins the game given in close games it frequently swings the outcome. In truth it also extends beyond charges/blocks to ticky tack fouls, but those tend to be used liberally by the refs to bring the team that is down considerably, back in the game.
Duke and Indiana are fine schools with lovely students, but when playing basketball at Assembly or Cameron, f*ck Duke and f*ck Indiana and their home cooked cheese, and to hell with the charge/block rules and how refs interpret them to ruin the true, fair outcome of games.
